  • Data center network system based on software-defined network and packet forwarding method, address resolution method, routing controller thereof
    Patent number: 10063470
    Abstract: A data center network system based on software-defined network (SDN) is provided. The data center network system includes a plurality of physical machines, a plurality of Ethernet switches, a plurality of OpenFlow switches connected to each other, and a central control apparatus. Each of the physical machines includes a virtual switch and at least one virtual machine. The virtual switches modify destination media access control (MAC) addresses of packets to MAC addresses of the OpenFlow switches, such that the Ethernet switches forward the packets received from the virtual switches to the corresponding OpenFlow switches according to the MAC addresses of the OpenFlow switches. The OpenFlow switches modify the destination media access control (MAC) addresses of the packets to MAC addresses of virtual machines, such that the Ethernet switches forward the packet received from the OpenFlow switches to the corresponding virtual switches.

  • Network controlling method and network controller
    Patent number: 9825850
    Abstract: A network controlling method and a network controller are provided. The network controlling method includes the following steps. A hybrid SDN-Ethernet system including a plurality of hosts, a plurality of Ethernet switches and m Software-defined networking switches (SDN switches) is provided. m is larger than or equal to 1. A first path according to at least one default spanning tree in the hybrid SDN-Ethernet system is obtained. m×k optional paths are obtained. Each of the m SDN switches is set as a beginning of each of k of the m×k optional paths. A second path is selected according to the m×k optional paths and the first path of the at least one default spanning tree.
